The landslide, which took place last year in September, triggered a massive tsunami in Dickson Fjord, creating puzzling tremors and a planet-wide “hum”, scientists said.
On September 16th, 2023 at 12:35 UTC, a 25.5 × 10 ^ 6 m 3 (33.4 × 10 ^ 6 cu yd) rockslide occurred on the slope of Dickson Fjord in Northeast Greenland. [1] [2] The rockslide impacted a gully glacier, leading to a rock and ice avalanche that entered the fjord causing a tsunami up to 200-metre-high (660 ft) tsunami and subsequent waves up to ...
A 650-foot tsunami in Greenland was the result of melting glacial ice that caused a landslide. The waves it created bounced back and forth for nine days.
It started with a melting glacier that set off a landslide, which triggered a tsunami. Then the Earth began to shake
On 16 September 2023 a large landslide originating 300–400 m (980–1,310 ft) above sea level entered Dickson Fjord, triggering a megatsunami exceeding 200 m (660 ft) in run-up height. A run-up of 60 m (200 ft) was observed along a 10 km (6.2 mi) stretch of coast, forming a seiche oscillation that decayed over a period of nine days.
In 1930 Norwegian ship Veslekari reached the head of Dickson Fjord and recorded a sounding of 568.75 m (1,866.0 ft), but sudden shoaling prevented the ship from anchoring. [4] On 16 September 2023, a significant landslide, consisting primarily of ice and rock, occurred in Dickson Fjord, triggering a 200-meter-high tsunami.

The term "megatsunami" has been defined by media and has no precise definition, although it is commonly taken to refer to tsunamis over 100 metres (330 ft) high. [2] A megatsunami is a separate class of event from an ordinary tsunami and is caused by different physical mechanisms.
